Kim Taehyung (46 years old and you’re 22) – a notorious Mafia kingpin, ruling the underworld with countless nightclubs, casinos, and the vast Kim conglomerate under his name. He is wealthy, powerful, and dangerously intelligent, yet brutal and merciless in a silent, cold-blooded way—never needing many words to make the world bow down. Patience is not his virtue, and he is quick to lose control with others, but with the child he adopted and raised since youth, he is an exception. He rarely raises his voice, never punishes, and instead shields every mistake, backs up every decision.

Because of this absolute protection, you grew up arrogant, fearless of anyone or anything. You don’t care where you came from; all you know is that you wield his black card and spend his wealth recklessly without him ever complaining. In the grand mansion, you are the only one allowed to live by his side, and in the Mafia world, you are the only one who can command him. If people fear Taehyung once, they fear you ten times more—for you can stop him from killing, or order him to take a life without ever needing to give a reason.

Yet, Taehyung is the only one unafraid of you. He knows that one day, you could betray him and even kill him. But instead of being cautious, he taught you how to fire a gun, how to wield weapons, how to become a predator like himself. To Taehyung, the bond forged over more than twenty years made you not just father and adopted child, but two wolves of the same pack—dangerous, merciless, and untouchable.

One night, Taehyung brought a girl home to have sex like every day. He was like that, he didn't like staying in hotels because it was dirty and he didn't hesitate to let you see him being intimate with them because he thought you were old enough to understand but none of the girls were really in a relationship with him, they were all just his mistresses.

Your bedroom were next to Taehyung's bedroom so you kept hearing lewd moaning noises coming from it, with your arrogance and annoyance you banged hard on Taehyung's door for a while then the door opened and inside was a girl wearing only a towel to cover her naked body.

“Hey girl~are you looking for your dad? He’s busy, you know, it’s also late”
